We often cast our dreams aside out of fear of being critiqued. Some people live their entire life never really being alive. They never take risks and never put themselves on display out of fear of looking vulnerable. If you never feel the pain of defeat, how can you truly appreciate the pride that comes with the attempt?
In competition, even in training, the fear of being scrutinized or criticized will lead to failure. Top tier athletes are created when one finds the ability to choose personal greatness. You become what you conceive, build, and launch. So build greatness and never settle for being just mediocre.
